Joint Special Operations University
and the Strategic Studies Department
The Joint Special Operations University (JSOU) provides its publications
to contribute toward expanding the body of knowledge about joint special
operations. JSOU publications advance the insights and recommendations
of national security professionals and the Special Operations Forces (SOF)
students and leaders for consideration by the SOF community and defense
leadership.
JSOU is the educational component of the United States Special Opera-
tions Command (USSOCOM), MacDill Air Force Base, Florida. The JSOU
mission is to educate SOF executive, senior, and intermediate leaders and
selected other national and international security decision makers, both
military and civilian, through teaching, outreach, and research in the
science and art of joint special operations. JSOU provides education to the
men and women of SOF and to those who enable the SOF mission in a joint
and interagency environment.
JSOU conducts research through its Strategic Studies Department where
effort centers upon the USSOCOM and United States SOF missions:
USSOCOM mission. USSOCOM provides fully capable and enabled
SOF to defend the nation’s interests in an environment characterized by
irregular warfare.
USSOF mission. USSOF conducts special operations to prepare the oper-
ational environment, prevent crisis, and respond with speed, aggression,
and lethality to achieve tactical through strategic effect.
The Strategic Studies Department also provides teaching and curriculum
support to Professional Military Education institutions—the staff colleges
and war colleges. It advances SOF strategic influence by its interaction in
academic, interagency, and United States military communities.

Foreword
The concept of hunter-killer operations deep within enemy territory
evokes a sense of excitement and adventure, especially for those
of us familiar with the exploits of Robert Rogers’ Rangers of the
18th century or the operations of Special Forces and Rangers in Afghani-
stan today. In this monograph, Colonel Joseph D. Celeski (U.S. Army, Ret.),
argues that hunter-killer teams be routinely established as part of our
standing Special Operations Forces (SOF). He states that guidelines for their
employment should be included in counterinsurgency (COIN) doctrine, and
Celeski further advises that the use of such forces should be a routine part of
the overall COIN effort. The idea is to aggressively pursue the enemy within
his own sanctuaries, disrupt his operations and sustainment, and neutralize
or destroy the adversary before he can threaten a friendly host government
or project extremist operations onto the world stage.
Celeski’s operational concept for hunter-killer operations bolsters the
command vision of U.S. Special Operations Command, which seeks to
develop a force capable of “distributed operations, within an environment
characterized by irregular warfare and asymmetric challenges.” 1
The hunter-
killer organization, with its strike units and teams, would be reinforced with
indigenous forces, much as we saw during the Vietnam War and the early
phases of the Afghanistan war. This kind of force could contribute toward
achieving the U.S. SOF mission to act with “… speed, aggression, and lethal-
ity to achieve tactical through strategic effect.” 2
Today U.S. national security is threatened by violent extremist groups
operating from sanctuaries in hard to reach areas of Afghanistan, Pakistan,
Yemen, Somalia, and similar areas in the Pacific Rim and Latin America. It
seems probable that there will be a marked increase in our need to disrupt
and destroy enemy forces in multiple sanctuaries around the globe as we
proceed to march through the 21st century. Celeski’s paper provides a vision
of the future SOF wherein hunter-killer teams could have a significant role
to play in finding, disrupting, and destroying the enemy.

About the Author
Mr. Joe Celeski is a senior
fellow with the JSOU
Strategic Studies Depart-
ment. His current research focuses
on irregular warfare/unconventional
warfare (IW/UW) with a specialty on
counterinsurgency (COIN), terrorism,
political warfare, urban warfare, joint
SOF warfighting, and senior leader
competencies. Retired from active duty
with the U.S. Army as a Special Forces
colonel, he served in a variety of United
States Special Operations Command
(USSOCOM) and staff positions for over
20 years of his 30-year Army career. Prior to retirement, he commanded the
3rd Special Forces Group (Airborne) at Fort Bragg, North Carolina (May
2002 to June 2004) and commanded coalition and joint SOF for two tours
in Afghanistan in support of Operation Enduring Freedom. He was a fully
qualified joint specialty officer. Additionally, he is a Middle East area expert,
trained in the Arabic language, and has served throughout the Middle East
and the Horn of Africa regions. In his capacity as the chief of staff and deputy
commander for the U.S. Special Forces Command at Fort Bragg, Colonel
Celeski was the project officer for force modernization initiatives, develop-
ment of the command’s Program Operating Memorandum input, and the
UW transformation initiatives. He was awarded the St. Philip Neri Bronze
Award from the Special Forces community in 2002 for his career work.
Mr. Celeski is a graduate of the Defense Language Institute (Modern
Standard Arabic), the U.S. Army Command and Staff College, the U.S. Air
Force Command and Staff College, the Marine Amphibious Warfare Course,
the Army Force Management School, and the U.S. Army War College. He

College in Carlisle, Pennsylvania. He will begin work toward his Ph.D. in
History from the University of Georgia in the spring of 2010.
Mr. Celeski has published works on the Somalia conflict and on the use
of Special Forces in Joint Urban Operations in UW in the U.S. Army John
F. Kennedy Special Warfare Center and School journal, Special Warfare. He
has submitted his first draft of “Special Forces History in Somalia Conflict,
1992-1995” for inclusion into Army SOF in Somalia 1992-1995, a fiscal year
2010 proposed publication sponsored by the U.S. Army Special Operations
Command historian. In addition, Mr. Celeski has been a keynote speaker
at a variety of forums, including the Assistant Secretary of Defense for
Special Operations and Low Intensity Conflict (ASD SO/LIC) sympo-
sium, the Association of United States Army (AUSA), Royal Canadian
War College, the Naval War College, and the Joint Forces Staff College on
matters of leadership, urban operations, and UW. He has also lectured in
a variety of international forums to include the Polish National Defense
University regional SOF symposium, the Special Operations Command

Hunter-Killer Teams:
Attacking Enemy Safe Havens
Introduction1.
Regular forces, indeed the most elite of highly professional regular
forces, Special Operations Forces (SOF), can wage war in an irregu-
lar, unconventional way. In fact, the history of warfare shows quite
clearly that if regulars are to prosper in campaigns against irregu-
lars, they are obliged to adopt at least some of the characteristics,
including the modus operandi, of the irregular enemy.3
— Colin S. Gray, Another Bloody Century: Future Warfare
During September 2008, public reporting in American and Paki-
stani press told of U.S. commandos purported conduct of large-
scale raids into the Pakistani border tribal region—presumably
authorized by the President of the United States—with unrestricted rules
of engagement not requiring U.S. regional command approval or acquies-
cence of the Pakistani government. The intent of the raids, as reported, was
to penetrate into the previously inaccessible safe haven enjoyed by Taliban
militants and Al Qaeda terrorists to destroy and disrupt their training bases
and to kill or capture their key leaders. U.S. military leaders and Afghan
President Karzai praised the action—that is, the solution to a long-standing
safe haven problem and to weak efforts heretofore on behalf of the Pakistani
security forces. Unfortunately, raids of this nature are of short duration and
not designed for persistent presence. Although they can be highly disruptive
to the enemy, they also can contribute to the adoption of a whack-a-mole
tactic to deny safe havens. Eventually, the enemy will adjust to this tactic
and make it harder for future raids to achieve success. The best counter safe

13.

haven line of operation involves a series of measures to achieve relentless
pressure; the line of effort has presence and persistence as attributes.
The most challenging strategic and operational dilemma currently facing
the U.S. military in both Operations Enduring Freedom and in the Horn
of Africa region stems from the enemy’s ease of withdrawal to inaccessible
areas, where he can operate from established safe havens and create opera-
tional bases to reform, refit, recruit, and relaunch attacks against coalition
forces. Adoption of counter safe haven measures should include the employ-
ment of hunter-killer teams as one of the options to challenge insurgent
perception of safety and invulnerability afforded by the inaccessibility sanc-
tuary offers them. When guerrillas or insurgents are challenged in their
own space, they are forced into a tempo of the friendly forces’ making and
often must abandon their base areas in order to survive. In addition, the
fear of U.S. hunter-killer teams persistently operating in and amongst one’s
perceived safe space provides its own psychological effect against one’s will
to continue the fight.
In any counterinsurgency (COIN) security line of operation, counterguer-
rilla activities are required as an offensive maneuver to throw off insurgent
attempts to occupy space and create alternate governance. Among the first
steps in any government response to an insurgency is holding and clear-
ing insurgent activities in the most vulnerable spots; this activity generally
requires the government to spread their resources in static holding posi-
tions, thus negating their freedom of maneuver to take on the insurgents
head-to-head. Simultaneously, it is at precisely the same time the govern-
ment is attempting to expand its security forces—military, paramilitary, and
police—to overmatch the insurgents and achieve a favorable ratio of forces
to reach a tipping point of security for its population. Conversely, insurgent
movements use this window of opportunity to tie down government forces,
thereby allowing time to build up their own armed action forces or build
forces for a move to the final, conventional offensive that would overwhelm
the government response. Thus at the operational and strategic levels it
becomes a race between the contestants—where the side that can prevent the
growth of a measurable combat response on the part of their enemy, while
maintaining legitimacy and the will to fight, may ultimately win.
The government response is often multidimensional—for example, hold-
ing and securing vulnerable portions of the country, maintaining legitimacy,
and solving grievances while simultaneously taking the offensive to the

14.

guerrillas. In taking the fight to the enemy, COIN practitioners adopt coun-
terguerrilla operations (a security line of operation). This means taking the
fight to the guerrillas, wherever they may be found, by raising the contact
rate between government forces and the insurgents. Against the insurgent
political arm, counterorganization measures are conducted to eliminate
enemy leadership and political organization. This includes manhunting
techniques. At the tactical level, aggressive patrolling operations to search
out guerrillas still form one of the best means for conventional forces.
Combined with raids, the enemy is kept off balance and denied the oppor-
tunity to choose the time and place of his engagements, spoiling his oppor-
tunities to protract or prolong the fight. Counterguerrilla patrols, however,
may not reach into inaccessible areas where insurgents seek to build their
bases and establish safe havens. Although conventional maneuver forces
(normally at company and battalion level) can conduct operations deep into
enemy-occupied territory, these often have a sweeping effect and conclude
after a short duration.
Insurgents enjoy the most freedom of maneuver in their safe havens
(bases), along their lines of communication, and in strategic rear areas, rela-
tively unhindered by the day-to-day activities of counterguerrilla operations.
It is within that shroud of security the guerrillas take the opportunity to
recruit, train, refit, and grow their forces, including developing the structure
for the establishment of a main force army. Unhindered by government
security forces interference, complacency about security and defense on
the part of the insurgent will begin
to set in, providing the opportunity
for specialized COIN forces to oper-
ate. An outstanding reference on
this aspect of irregular warfare is the
2007 publication edited by Michael
Innes, Denial of Sanctuary: Understanding Terrorist Safe Haven. One proven
method of disrupting insurgents or terrorists enjoying safe haven has been
the employment of hunter-killer teams.
The purpose of this monograph is to examine the characteristics and
attributes of safe havens, explore options for counter safe haven measures,
and then focus the analysis on the historical and contemporary U.S. mili-
tary employment of one of those measures—hunter-killer team opera-
tions. The monograph explores previous doctrinal attempts to describe the

employment of U.S. military units conducting counter safe haven measures
to derive a proposed definition for COIN hunter-killer operations. It also
examines the American historical use of predominantly specialized, light
infantry employed as counterguerrillas with the mission to penetrate and
operate deep into enemy safe havens.
The overarching lessons gleaned from the American military employ-
ment of hunter-killer operations will form the basis for principles required
for doctrinal employment of hunter-killer operations in COIN and other
irregular warfare scenarios. The research of the monograph concludes with
a proposed recommendation on the specific forming and use of hunter-killer
organizations as a viable measure for counter safe haven activities in any
conflict with irregular warfare adversaries for doctrinal inclusion in future
revisions of COIN or irregular warfare literature. Additionally, the mono-
graph provides recommendations for the establishment of formal hunter-
killer organizations, at least within the USSOCOM component capability,
under the operational art of unconventional warfare (UW).
If seen as viable, the hunter-killer concept deserves inclusion into future
revisions of irregular warfare doctrine. Currently, doctrine is lacking on the
specific proscription of counter safe haven measures that can be conducted
by specialized forces in hunter-killer configurations (procedures on the
attack and harassment against adversary morale, their sustainment system
[war-making capabilities], and their source of strength and support—a
witting populace). These activities are important to the COIN force because
they can contribute to the exhaustion and erosion of insurgent forces while
they are in their safe havens.
The research thesis is to answer the question: Is the employment of
hunter-killer operations, as a counter safe haven measure in COIN, a sound
doctrinal concept for the U.S. military? The research did not explore foreign
concepts unless they were useful to the development of U.S. doctrine, nor
the concept of hunter-killer operations used by conventional forces against
conventional force adversaries, although they may be unorthodox (such as
operations to detect German U-boats in World War II). This monograph
also does not include the common usage of technological hunter-killer oper-
ations—the so-called sensor-to-shooter concept (such as observer aircraft
hunting for enemy tanks, then directing the efforts of the killer)—in order
to focus uniquely on COIN counter safe haven requirements.

Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
Logic abounds in the annals of warfare on the military dictum to take
the fight to the enemy. Irregular warfare is no different. Its defensive compo-
nent—the use of irregulars as auxiliary—is used to augment the maneuver
of conventional force or provide economy-of-force options. Its offensive
component resembles a variety of tools in a toolkit for irregular warfare
employment: counterguerrilla operations, counterorganization operations,
counter safe haven operations, pseudo-operations, manhunting, and the
most feared by irregular warfare adversaries, the employment of hunter-
killer teams.

Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
Background, Definition and Doctrine2.
In the guerrilla areas, the governing authorities should commence
what we shall call a territorial offence. As in the cases of territorial
defence and consolidation, territorial offence will require assign-
ment of small military detachments to a large number of specific
zones. Although these detachments should establish local opera-
tional bases, they should not be garrisoned in posts. Rather, they
should continuously ‘nomad’, using ‘whirlwind’ (tourbillon) type
tactics—as the French describe them.4
— John J. McCuen, The Art of Counter-Revolutionary War
To be considered as military doctrine a warfighting concept should
be accepted by military professionals as an agreed upon means of
practical and common usage of employing military resources. The
concept should generally solve a dilemma posed by the nature of war—
for example, offense to defeat a defense, amphibious operations to gain
lodgment in enemy territory, and interdiction to deny the enemy lines of
communication. Finally, the intended action should be grounded in some
theoretical aspect of war that has stood the test of time (a belief).
An objective of this monograph is to explore why hunter-killer operations
against enemy safe havens have had little doctrinal capture, particularly as
the Department of Defense (DoD) shifts its military art in recognition of
the Irregular Warfare Joint Operating Concept. As a framework for this
discussion and after conducting the research, the following definition is
proposed:
Hunter-killer operations are prolonged operations conducted in
irregular warfare by a unique and specifically organized force, in
conjunction with an indigenous force, against irregular warfare
adversaries by operating behind the lines or in hostile, safe haven, or
semipermissive environments, employing unorthodox tactics, for the
sole purpose of achieving attrition and punitive actions predominantly
against the personnel, leadership, and resources of the enemy.
This definition has as its base a UW solution to an unconventional prob-
lem. The unconventional problem is the lack of access into insurgent safe

18.

JSOU Report 10-1
havens due to political factors, military limitations, and/or geography (and
could also include seasonal weather).
Insurgency theorists (most notably Robert Taber, War of the Flea) discuss
the requirement on the part of the insurgent to juxtaposition one’s time,
space, and will—elements of strategic art—against the competing actions
of the government. For space, insurgents draw strength from having bases
and safe areas to operate from, essential to the building and development
of an action arm, a political process (alternate governance), and the ability
to hide from security forces, thus contributing to the protraction of the
conflict (and to ensure survival).
Protraction of conflict has its roots in war of exhaustion and war of
erosion theories, made famous by the writings of Mao. Time can be on the
side of the irregular warfare adversary if used with other strategic initiatives.
The body of conflict theory is also clear that war is a clash of wills; at the
military level, using force successfully against the enemy’s force becomes
one of the paths to achieve strategic objectives.
In most COIN theory, no one course of action chosen from elemental
truths about the conduct of this type of irregular warfare will guarantee
success; rather, the COIN leader becomes a virtuoso of applying contextually
agreed upon COIN measures, hopefully with the right mix and balance, to
achieve the political ends of the struggle. In the aggregate, these measures
historically (and doctrinally) include not only political and psychosocial
activities but also some form of the often mentioned clear, hold, build and
find, fix, destroy. To clear and hold in COIN requires a static force (the
defensive). To find and fix, then destroy requires an active force, basically
consisting of offensive components, which include counterguerrilla forces
and other specialized forces whose purpose is to help improve the contact
rate and raise the attrition level of the insurgent to buy time for other popu-
lace security and political solutions to work.
Insurgents often enjoy the ability to operate at “the time and place of
their choosing”; when they do, COIN forces now know where they are and
their capabilities. In these cases, casualty rates tend to favor the conven-
tional, government forces. The larger challenge, if counterinsurgents are to
defeat or neutralize the action arm and to destroy the insurgent’s base of
support (bases and safe havens), is to take offensive actions to thwart insur-
gent moves to operate between the seams of a country’s vital infrastructure
and its population centers, while enjoying the ability to retreat to safety.

Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
Properly conducted, the military line of operation in a COIN effort
becomes the blend of antimeasures, countermeasures, and offensive
measures. There is a range of measures available to the counterinsurgent;
however, most of these measures remain at the tactic, technique, and proce-
dural level of handbooks rather than incorporated into our doctrinal knowl-
edge of irregular warfare. Table 1 shows a range of operations consistently
agreed upon and utilized during irregular warfare—a belief of how COIN
forces approach attacking insurgent time, space, and will while simultane-
ously providing force-on-force options to attrit the enemy.

Insurgency theory posits the strategic balance of time, space, and will
arrayed against government strengths as a means to achieve a political
victory, all based on theories of war to exhaust or erode populace support
for the government. In the modern context, legitimate and criminal busi-
ness enterprise (or external support mechanisms that may replace lack of

20.
10
JSOU Report 10-1
external state sponsorship) are also critical to the viability of any insurgency.
Friendly military options are a mix of anti, counter and offensive measures
to spoil these five strengths. These can be used to keep the enemy off balance
while the political and civil measures of an effective IDAD plan take time
to work.
This discussion rests on the offensive components of COIN and to some
extent broader applications in other irregular warfare scenarios. Hunter-
killer operations are one of the options used by COIN forces to go on the
offensive against insurgents, particularly as a counter safe haven measure.
Because there are a variety of options that can be confused with pure hunter-
killer concepts, a brief discussion of their characteristics will distinguish
them from the COIN hunter-killer term—a useful point for doctrinal distinc-
tion. Each option discussed below embodies a particular effect; hunter-killer
operations differ in that most of these effects can be combined to achieve a
synergy aimed toward one objective—cumulative activities over time that
contribute to the erosion or exhaustion of the insurgent:
Raida. is a tactical action conducted behind enemy lines (or in enemy-
controlled areas) by conventional infantry or elite or “shock” infantry
with a specific purpose in mind. (These elite units are often considered
commandos.) The raid may have tactical, operational, or strategic
value. Raids generally do not achieve coup-de-main status. Raids are
intended to be short duration missions whereby the raiding force
immediately withdraws after the operation back to its own friendly
lines; the survival of the raiding force is often predicated on this
extraction before enemy forces respond. Raiders can hold ground
momentarily, but often require a linking-up action by larger conven-
tional forces if the ground, or objective, is to be secured for friendly
forces. Larger, deep-penetration raids by conventional forces can also
be conducted as punitive operations.
Interdictionb. targets enemy lines of communication and support struc-
ture in order to deny war-making capability. Interdiction operations
include various targeting methodologies, combined with detailed
intelligence and confirming reconnaissance, to increase measures of
success. Interdiction can be performed with direct action, airpower,
or with standoff capabilities. Sabotage of war materials is one of the
unconventional measures to conduct interdiction.

21.

Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
Manhuntingc. is the specific targeting of leadership and key personnel
within an enemy organization. It is a counterorganization technique.
In military parlance, manhunting is characterized by all the activities
to conduct high value target (HVT) operations against individuals to
decapitate an organization. Manhunting techniques often resemble law
enforcement measures used to bring a criminal to justice. Manhunt-
ing is human-intelligence (HUMINT) intensive.
Counterorganizationd. is the means used to defeat the insurgent politi-
cal arm and its organizations. In insurgency, the enemy may attempt
to establish alternate governance with their political arm, first as a
competing option to the populace’s loyalty, then as a mechanism
to assume the trappings of state and secure power once victory is
achieved. In these cases, political and front organizations are created
to counteract the legitimate symbols of state, at all levels. The insurgent
political arm is also a necessary means to mobilize the populace. Insur-
gent politics may ultimately require the ability to handle diplomacy
at the international level. Counterorganization measures consist of
actions to identify, penetrate, and neutralize insurgent political orga-
nizations. Subversion, apprehension, or neutralization of members of
the enemy’s political arm, combined with a counterideology campaign,
are just some of the activities taken by a government threatened by
shadow governments. Many of the successful counterorganization
campaigns adopted the combination of military, intelligence, and
policing in joint task-force organizations to achieve unified action
on this front. Counterorganization should not be confused with
countermobilization (denying the form of alternate governance) and
counterguerrilla actions (securing the populace and isolating them
from the insurgents).
Pseudo-operationse. are most often paramilitary police operations
conducted to gain intelligence on the enemy. Pseudo-organizations
adopt the appearance of the guerrilla in order to gain access to the
enemy’s operational area. While combat may occur, this is not the
intended purpose of the operation. The best pseudo-operations are
those that incorporate turned insurgents.
The usefulness of hunter-killer operations is they could achieve many of
these results within the objective of denying the enemy space and destroying

22.

JSOU Report 10-1
his will through erosion and exhaustion. Hunter-killer operational utility
derives from employing an effective economy-of-force option, achieving
persistence by operating in the same space and conditions of the enemy,
while achieving a military and psychological impact out of proportion to
its size (operational or strategic performance is achieved).
U.S. irregular warfare doctrine has never quite pinned down this concept
in detail. COIN doctrine and emerging irregular warfare doctrine quite
adequately address the need to deny insurgents access to safe havens and
support (tacit/unwitting; internal/external) but lack in specifics for prin-
ciples and application of the measures needed. Notwithstanding, good
counterinsurgents have always devised a means for attacking the enemy in
safe havens. Either these were on the spot, intuitive, individual decisions
or derived from lessons passed from earlier practitioners without adoption
into doctrinal literature, even though some doctrinal writings through-
out history have at least come close to describing the role of hunter-killer
teams.
The earliest attempt to capture hunter-killer concepts evolved from
Benjamin Church’s personal memoir of his ranging activities with specially
formed militia into hostile territory during King Philip’s War (1675 to 1676).
These written experiences were incorporated into techniques used by Robert
Rogers, who in the French and Indian War developed his now-famous rules
for the conduct of deep reconnaissance raids.
Much of what early counterinsurgents understood about offensive opera-
tions against irregulars in inaccessible territory may have been derived from
reading Colonel C. E. Callwell’s monumental work Small Wars: Their Prin-
ciples and Practices, which he published in final, revised form in 1899. Call-
well described a “doctrinal” approach of flying columns (superior maneuver
and mobility to the irregular) and specified the purpose of raids in irregular
warfare (“… kill them or to wound them, or at least to hunt them from their
homes and then to destroy or carry off their belongings” 5
), combined with
the need to match the enemy and adapt. However, U.S. irregular warfare
experts largely relied on the personal experiences and accounts of previous
practitioners through the venue of lessons learned passed on generationally.
U.S. Army operations against the Southwest Indians, the Texas Rangers
experiences against the Plains Indians, and the COIN experience from the
Philippine War lost doctrinal capture and appeal in the shadow and subse-
quent deployment for World War I.

It took the cumulative experience of the U.S. Marine Corps, over many
years, to codify military activities conducted deep in enemy territory in its
Small Wars Manual, published in 1940. Much of Callwell’s work appears to
have made its way into the Small Wars Manual, which also set the standard
for utilizing task-organized conventional forces to conduct these specialized
operations, such as deep raids. (Specially organized hunter-killer forces to
conduct this task were still far in the future.)
The Small Wars Manual developed a variation on Callwell’s theme; there
would be a variety of means to challenge guerrillas on their turf: flying
columns, mobile columns, and roving patrols (all still comprised of conven-
tional forces). The mobile column differed from a flying column only in its
range and reliance on a base of supply. Of interest was the roving patrol
concept, the clearest capturing of doctrinal employment of hunter-killer
teams:
A roving patrol (at 5-21 in the manual) is a self-sustaining detachmenta.
of more or less independent nature. It usually operates within an
assigned zone and as a rule has much freedom of action. As distin-
guished from other patrols, it is capable of operating away from its
base for an indefinite period of time. Missions generally assigned
include a relentless pursuit of guerilla groups continuing until their
disorganization is practically complete.
This method is particularly applicable when large bands are known tob.
exist and the locality of their depredations is approximately known.
Such patrols are often employed in conjunction with other methods
of operations.
Of course, World War II diminished the fascination with small wars. By
World War II, the American militia and independent volunteer system was
gone (which eliminated the U.S. pool of outdoorsmen adept at ranging) to
be replaced by National Guard and Reserve structures tailored for conven-
tional war (because armies were required to fight armies). World War II also
shifted the emphasis of elite and specialized military unit employment from
ranging to one of reconnaissance, shock infantry, and raiding (e.g., Rang-
ers, U.S. Marine Corps Raiders, and 1st Special Service Force). Finally, the
American military was not confronted with an irregular warfare enemy in
World War II, so it came out of the experience with an overall penchant for

24.
14
JSOU Report 10-1
conventional warfare, even though much had been learned by the Office of
Strategic Services (OSS) conducting guerrilla warfare activities.
Prior to the Vietnam War, it was the doctrine of other nations that
expounded on offensive activities to challenge insurgent space. While not
American doctrinal solutions, these examples did provide some framework
for further U.S. military doctrinal approaches to COIN techniques. Roger
Trinquier’s treatise, Modern Warfare: A French View of Counterinsurgency,
Sir Robert Thompson’s work, Defeating Communist Insurgency, and David
Galula’s Counterinsurgency Warfare: Theory and Practice contain examples
for offensive actions within insurgent territory to attack bases and attrit the
enemy (e.g., intervention units, some form of pursuit commandos, pseudo-
organizations, and Ranger-type organizations).
One of the first uniquely American-derived doctrinal approaches to
antiguerrilla activities after World War II involving hunter-killer opera-
tions was offered by Lt Col Edward G. Lansdale during the early 1950s,
when he served as an UW liaison officer to Ramon Magsaysay, the Philip-
pine Secretary of National Defense. Lansdale assisted in COIN efforts to
defeat the communist-inspired Hukbalahap insurgency. From observations
and front-line experience, Lansdale consolidated his thoughts on effective,
antiguerrilla operations. While the document, “Operations Against Guer-
rilla Forces” (undated), was supported by the Military Assistance Advisory
Group (MAAG) chief of the U.S. embassy in Manila, its restricted nature
prevented widespread sharing among military professional and doctrinal
institutions. Thus its tenets for offensive COIN, by forming specialized anti-
guerrilla units, did not become mainstream. Lansdale called for the creation
of special antiguerrilla units to penetrate and destroy insurgent personnel
and infrastructure, arguing for small-unit, broadly scoped missions and
specifically warned of the need to maintain and support special antiguer-
rilla units to increase their viability for extended operations (the caveat was
against retasking conventional infantry for this purpose).6
COIN doctrine developed by the U.S. during and after the Vietnam War
still did not address offensive actions into enemy sanctuaries as anything
other than pursuit, reconnaissance, interdiction, or raids (e.g., the actions
of Special Operations Group and the U.S. Special Forces B52 organization).
However, it was still apparent to counterinsurgents that denial of safe havens
(the term sanctuary was used in most military literature of that day) was
a key component of COIN success. The Department of the Army released

Perhaps a limiting political factor in modern COIN may have unintention-
ally affected doctrinal approaches, then and now: the diplomatic repercus-
sions of violating the sovereignty of another country.
The one clear approach for taking the fight to enemy-dominated territory
emanated from UW approaches developed by the U.S. Army Special Forces.
Still not explicitly stating a unique role for hunter-killer operations, FM 31-21,
Guerrilla Warfare and Special Forces Operations (Headquarters, Depart-
ment of the Army, September 1961) came close in its page 130 discussion
of attrition measures and interdiction operations conducted by irregular,
indigenous forces:
Section III. Interdiction. 117. General
UWa. forces use interdiction as the primary means of accomplish-
ing operational objectives. Interdiction is designed to prevent or
hinder, by any means, enemy use of an area or route. Interdiction
is the cumulative effect of numerous smaller offensive operations
such as raids, ambushes, mining, and sniping. Enemy areas or
routes that offer the most vulnerable and lucrative targets for
interdiction are industrial facilities, military installations, and
lines of communication.
The results of planned interdiction programs are.b.
Effective interference with the movement of personnel, supplies,•
equipment, and raw material
Destruction of storage and production facilities•

Although UW doctrine was specifically developed to employ Special
Forces in consort with an indigenous resistance movement, the U.S. Special
Forces during the Vietnam War adapted this doctrine for use in security
force assistance operations and created Mobile Guerrilla Forces (auxiliary)
to take the fight to the Viet Cong in their base areas. Between this approach,
borrowing of foreign doctrine, and the earlier thoughts of the U.S. Marine
Corps on roving patrols, the elements for development of hunter-killer
operations in irregular warfare doctrine could have been framed.
COIN’s resurgence in doctrinal appeal came to the forefront with
the involvement of U.S. forces after 9/11 in the two insurgencies in Iraq
and Afghanistan. (We can also add Operation Enduring Freedom in the
Philippines.)
The U.S. collective doctrinal approach to COIN is now embodied in
FM 3-24, Counterinsurgency. Chapter 1 clearly describes not only the benefits
that sanctuary (now referred to as safe haven) provides insurgents but also
the doctrinal prescription: “Effective COIN operations work to eliminate
sanctuaries.” 7
Further in the chapter (section I-98), the following is offered:
“Timely, resolute counterinsurgent actions to exploit poor enemy base loca-
tions and eliminate or disrupt good ones can significantly weaken an insur-
gency.” The field manual is also quite clear that the preferred method to
achieve this disruption is through the offensive actions of land forces and
an effective targeting system. However, there exists little discussion on the
role of employing hunter-killer teams or indigenous hunter-killer teams as
part of these disruptive options. Even less are any works on the analysis and
appreciation of the framework and characteristics of safe havens.
To achieve the level of doctrinal acceptance for hunter-killer operations,
the concept must be recognized as an American way of war; it certainly has
its historical antecedents. There must be a set of unifying principles for its
employment, and key to doctrine, an agreed upon definition of its nature;
this monograph supports that requirement. A thorough understanding of
the characteristics and attributes of safe havens and their impact on friendly
forces is necessary to develop counter safe haven measures; see chapter 3.
To refine this thesis, a review of the American historical approaches in the
employment of hunter-killer operations is warranted, primarily to ascertain
their advantages and disadvantages, utility and to define the boundaries for
the development of operating principles. This work examines the American
historical approaches on the use of hunter-killer methodologies during its

Safe Havens4.
…. it’s very clear to us that Al Qaeda has been able over the past
18 months or so to establish a safe haven along the Afghanistan-
Pakistan border areas that they have not enjoyed before, that they
are bringing operatives into that region for training, operatives
that wouldn’t attract your attention if they were going through the
Customs line at Dulles with you when you’re coming back from
overseas.
— LTG Michael Hayden, CIA director, 30 March 2008
The ability of terrorists and other irregular warfare adversaries to
conduct operations from a sanctuary—hereafter referred to in more
common usage as safe haven—increases the potential success of the
insurgent or terrorist in their struggles against government forces. Deny-
ing safe haven, therefore, is an essential part of any counterstrategy. For
instance, the use of Pakistan’s tribal areas as a safe haven by the Taliban
and Al Qaeda present allied forces with a large strategic dilemma if not
addressed (the protraction of the war and the weakening of the government
will to prosecute the campaign). The most imposing future security threat
may not be rogue or strong states, but rather the emergence of weak and
failing states that can ultimately be used as safe havens by our enemies—
such as we are now seeing in the Horn of Africa region, Somalia and Yemen.
Worse, the linking together of multiple safe havens creates a network of
imposing challenges to security forces charged with protection of national
sovereignty.
Current methodologies for the creation of campaign plans have now
recognized the need for a commander’s appreciation to frame the problem
prior to any staff entering the military decision-making process to develop
the architecture of the campaign plan. This chapter provides a way of looking
at the problem of enemy safe havens when conducting initial assessments.
The Role of Safe Havens
This aspect of the generational challenge—persistent conflict against violent
extremism—posed by transnational threats operating from safe havens was
clearly identified in the findings of The 9/11 Commission Report:

29.

Reliable communications between coordinators and operativesf.
Opportunity to test the workability of the plan.g. 8
After The 9/11 Commission Report, the U.S. Department of State (DoS)
conducted a refined study of the desired attributes that may or may not
make a place a safe haven in order to formulate a working definition of safe
havens. That definition would be useful for the conduct of diplomacy when
considering threats to national sovereignty. The DoS definition additionally
highlighted places where the enemy could operate in relative security and
perform the functions noted above. Regardless of the definitional sources
on the safe haven phenomenon, the following definition offered by the
Interagency Intelligence Community on Terrorism (IICT) serves best for
the purpose of this monograph (and expanding the definition to include
insurgents):
A safe haven is ‘… an area where terrorists are able to gather in rela-
tive security and in sufficient numbers to engage in activities that
constitute a threat to U.S. national security. Such activities include
attack preparations, training, fundraising, and recruitment often
conducted in unsecured or undergoverned geographic areas.’ 9

Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
Features of Safe Havens
What are the desired features making a location attractive as a safe haven
or a potential future safe haven? One of the key, critical vulnerabilities of
insurgent and terrorist organizations is the need for secrecy and security in
order to operate. Counter safe haven operations are often aimed at exposing
or dislodging irregular warfare adversaries in these two areas—secrecy and
security—to create a third vulnerability—movement. Another important
vulnerability is the enemy’s need for the support of the populace, making
isolating the populace from the enemy an often-considered COIN and
combating terrorism tool. Thus, preferred features of the safe haven must
include the ability to hide in plain sight (even better if the position is near
the area of operations), to be located where it is physically nonaccessible by
government security forces, and with the ability for the enemy to operate
in a secure manner—free from police, intelligence operatives, and legal
systems.
A supporting populace is also highly desirable in order to provide venues
for recruitment as well as needed logistical and financial support. However,
the enemy can still operate in a safe haven without popular support; a popu-
lation can be terrorized and intimidated into acquiescing to the demands of
the enemy or at least not turning the enemy over to government forces.
Another desired feature is the ability to get into and out of the safe
haven to conduct operations, requiring nonrestrictive transit routes and
transportation assets. This feature is further enhanced by establishing the
safe haven near porous borders and along illicit rat lines already in use for
smuggling and other criminal activities where the participants are adept at
evading law enforcement and customs agents. A final highly desired feature
would be having connectivity to cyber systems.
Framing the Environment
Prior to consideration of any counter safe haven operation, the safe haven
area should be thoroughly analyzed with regard to its composition. Is it an
ungoverned or undergoverned area? Is it truly a safe haven that provides
sanctuary, or is it merely a base of operations? Is the area an ethnic, sepa-
ratist region or is it part of the country-wide insurgency? Or like the FARC
operations in Columbia, is it an area for a criminal business enterprise?
Clear understanding of the environmental makeup of the safe haven and

31.
22
JSOU Report 10-1
the motivations of its actors will assist in the shaping of the counter safe
haven plan.
Safe havens can also be categorized by function and by geography. Func-
tional safe havens include refugee camps, prisons, diasporas, academia,
and ideology (a supportive, cultural affinity to support the terrorists or
insurgents). Geographical types (physical spaces) of safe havens include
urban, rural, and virtual.
During their analysis, counterterrorists and counterinsurgent planners
identify issues that may place restrictions and limitations on their ability to
conduct counter safe haven operations. Imposing physical terrain and issues
of sovereignty can limit operations to only the fringes of the safe haven
area. Security forces may be nonindigenous to the area and even further
hampered by rules of engagement. The skills and capabilities of the security
forces require review to ascertain the correct ways and means to achieve the
ends. As an example, brute force and repression can be used to clear a safe
haven if the security forces do not have finesse; the second and third order
effect, however, may result in huge refugee populations and a devastated
area now requiring an expensive rebuild. Clearing a safe haven could end
up as a protracted operation—the government must have the will and time
needed to outlast the enemy and see the operation to its conclusion.10
Counter Safe Haven Approaches
The following approaches to denying or countering adversaries operating
in safe havens were derived from historical examples of irregular warfare
conflicts since the end of World War II. One may wish for the case where
the indigenous population within the safe haven rises up against the terror-
ists or insurgents, but this rarely happens. The framing of the safe haven
environment during assessment and analysis will often dictate the approach
considered. The following are common approaches that can be used as a line
of effort within campaign plans (individually, or in the aggregate):
Isolate, manage, and contain the safe haven (includes bordera.
interdiction)
A policing, law enforcement, and intelligence approachb.
Brute force intervention (invasion, interdiction, sweeping)c.

Unconventional warfare.e.

32.

The best approach, historically, is one in which the host nation with the
problem solves it without external assistance.
Counter Safe Haven Techniques for Security Forces
The following measures should be considered for development of a counter
safe haven plan. The plan will be multidisciplinary, with the combination
of several of the measures applied in consort with one another:
Enhance border control, customs, and immigration services.a.
Prepare human terrain databases and social-cultural mapping, applyb.
additional population control measures (e.g., control of resources,
biometrics, and identification cards), and co-opt the local populace
and solve grievances to isolate population from the enemy.

tivation operations in the safe haven.
Simultaneously attack any criminal business enterprises.d.
Develop and employ specially trained forces (e.g., border interdiction,e.
hunter-killer teams, and pseudo-operations teams).
Employ an interdiction and targeting plan throughout the safef.

(kinetic).
During the Algerian War, the French recognized the insurgent use of
sanctuary across the borders in Tunisia and Morocco. The French applied
various techniques to isolate the National Liberation Army (ALN) inside the
safe havens through the building of an effective barrier system: the Morice
Line along the Tunisian border and the Pedron Line along the Moroccan
border. The barriers—barrages—consisted of wire fences augmented with
lights and minefields and were eventually very effective in stopping enemy
infiltration with a kill rate of over 85 percent. Over 40,000 troops were
assigned to static posts along these barriers supplemented with mobile

33.
24
JSOU Report 10-1
columns to react to penetrations. In consort with the border barrages,
French naval forces implemented a campaign of coastal surveillance and
high seas interdiction to close down arms smuggling. These measures
taken collectively forced the ALN to continue only with guerrilla opera-
tions while thwarting attempts to conduct more aggressive, mobile warfare
operations.
Summary
Countering an adversary safe haven is a multidimensional problem, often
with no single solution. Correctly framing the problem of safe haven (its
characteristics and environment) helps to identify the approaches and tech-
niques required to effectively achieve its elimination or at best, denial to
enemy forces. Some of the key vulnerabilities of terrorists and insurgents
who operate within safe havens are organizational security, physical secu-
rity, and often the need for a supporting populace. Government legitimacy,
effective security forces, and countermobilization of the population to sepa-
rate them from the threat are among the most effective tools in eliminating
or denying safe haven creation.
A wide variety of military, policing, and law enforcement measures are
available to the counterterrorist and counterinsurgent to achieve the desired
effects on adversary safe havens. One of those measures discussed here is
the employment of hunter-killer teams within the safe haven. Historically,
the U.S. military has employed some form of this technique based on the
demands of the irregular warfare environment and yet failed to adequately
codify this approach in doctrine. Chapter 4 reviews American military
employment of hunter-killer type formations throughout U.S. history to
derive the advantages and disadvantages of their use, to capture key lessons
learned about their operations, and to synthesize the best practices observed
and employed to capture hunter-killer team employment principles (chapter
5). An understanding of these principles will support the formulation of
future COIN and counterterrorism doctrinal input on this subject, particu-
larly in the wider area of counter safe haven operations.

The American Historical Experience in4.
Hunter-Killer Operations
Scouts without a peer, superb in woodcraft, the Indians fought
the total warfare of the barbarian hordes of the past and of the
‘civilized’ nations of the futures. Such was the military legacy of
the Indians to the garrison of Fort Stanwix, as to their forefathers
before them and to the soldiers who would come after them, an
invaluable bequest for all our later wars through Korea. The art of
using cover, of infiltration, of ambush, and sudden surprise attack,
of mobility…. Ranger companies before and during the Revolution
practiced Indian tactics to the hilt, as would their counterparts on
into the twentieth century. In no small measure the Indian Wars
made the American Army the effective fighting force it became.11

Doctrine can be informed by historical experience. In most scenar-
ios where the American military was faced with an irregular
warfare adversary, some form of ranging or hunter-killer units
were employed as a response to take the fight deep into enemy territory. A
review of those experiences in various irregular wars fought by America can
establish the acceptance and utility of employing hunter-killer operations
as part of any American way of irregular warfare.
The U.S. military hunter-killer team employment and counter safe haven
experiences can be divided for study between the preindustrial period of
colonial and early American era to post-World War II and beyond. Some
reasons for the break and the differences between the two periods follow:
Rules of engagement became more restrictive and humane to limita.

lar warfare begin to become scorned by more professional military
leaders).

attributes to range and conduct hunter-killer activities as ad hoc
formations.
Of most consequence, World War II changed the role of irregular rang-
ing skills of elite light-infantry units to creation of special raider and
commando-style units patterned upon European doctrine (even though
the U.S. Army still retained Ranger-type formations). Unfortunately, the
ranging skill of the light infantryman (independent units adopting enemy
tactics and operating for extended periods in nonpermissive areas) becomes
lost in the conventional nature of the war as they soon become shock infan-
try, raiders, and long-range reconnaissance units.
Colonial and Early American Period of Hunter-Killer Operations
The American military experience with hunter-killer operations in enemy
safe havens began in a world in which we find ourselves today. It was during
a clash of civilizations throughout the 1600s and 1700s where expanding,
foreign imperialism crashed into indigenous populations and culture; indig-
enous cultures were manipulated by contending states to provide irregular
warriors for the fight. It was a conflict between liberally governed soci-
eties, ruled under a sense of recognized legitimacy, against substate and
tribal warriors. Competing ideologies of refined culture versus savagery
and barbarism formed the backdrop of warfare amongst combatants and
noncombatants alike. Whole populations lived in terror of massacre, behead-
ings, torture, wretched imprisonment if captured, and the destruction of
homelands and economies.
These conditions created a unique way of early-American war on the
frontier and fostered the employment of ranging tactics as hunter-killer
operations against irregulars in their safe havens. The operational style of
ranging initially consisted of patrolling between frontier forts (to detect
enemy activities) as well as scouting and raiding if warranted. Thus the
name for these early hunter-killer type militia units: Rangers. The follow-
ing examples illustrate various roles and missions of the early Rangers and
the pros and cons of their employment as hunter-killer units. The most
comprehensive work on this way of war and a complement to any library
on irregular warfare is John Grenier’s book, The First Way of War: Ameri-
can War Making on the Frontier. Hunter-killer methods became the most
effective mode of early American irregular warfare military art. Those tasks

36.
27
Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
required long-range penetration into enemy territory and a laundry list
of destructive measures to accomplish once there, all contributing to the
attritional nature of wars of exhaustion against irregular warriors.
Attacking and destroying Indian noncombatant populations
remained the American, particularly frontiersmen, preferred way
of waging war from the early sixteenth through early nineteenth
centuries, even after the formation of the regular American Army
and its attempts to move toward the eighteenth century European
norm of limited war.12
King Philip’s War, 1675 to 1676. The expanding land desires of the early
settlers in southern New England (Massachusetts Bay Colony, Swansea,
Plymouth Colony, Rhode Island, Connecticut), combined with growing
disdain on the part of colonists for the incompatibility with European
culture and values of the various indigenous Indian tribes populating the
region, led to the first outbreak of formal military operations. It reached
campaign scale during King Philip’s War, fought between 1675 and 1676,
against the backdrop of Europe’s 30 Years War.
King Philip (with the Wampanoag Indian name of Metacom) led the
eastern American Indian tribes of the Wampanoag, Narragansett, Nipmuc,
and others in an attack against the colonists in June 1675, in the southern
border region of the Plymouth Colony. Before the war ended, thousands of
towns, settlements, and homes of American settlers were destroyed, over
800 lives lost amongst the settlers and approximately 3,000 losses amongst
the Native American populace (resulting in the decimation of the eastern-
American Indian tribes).13
Early colonial military defense consisted of a basic self-reliance on an
armed populace and the establishment of a mutually supporting colonial
militia system, all backed up with a series of fortified houses and blockhouses
stretching across the frontier. If attacked, the citizenry would rally into the
fortified positions and allow the militia to patrol and roam between them
in an attempt to clear away the Indians. American militias were trained in
accordance with European military tactics involving lines of infantrymen
delivering volley fire. The Indians used guerrilla-like tactics, first raiding,
then disappearing into forests and swamps as refuge and sanctuary.
As in all insurgency-like conflicts, the enemy’s elusiveness plagued
efforts to bring on decisive military battle. In recognition of the need to

37.
28
JSOU Report 10-1
take the fight to the Indian warriors, Governor Winslow (Plymouth Colony)
appointed Benjamin Church as the commander of the first full-time, inde-
pendent company of Ranger militia. Comprised of both expert frontiers-
men and Indian volunteers (initially about 60 Englishmen and 140 Indian
irregulars), Benjamin Church employed his unit as the first officially sanc-
tioned American ranging unit with a clear mandate for a hunter-killer type
of operation:
… a force specially designed to search out the remnants of the enemy
wherever they may lurk and beat them at their own tricks of forest
warfare.14
Captain Church was well known—a famous Indian fighter—and had a
vast knowledge of the frontier territory. His unorthodox leadership style,
with a flair for the dramatic, made him a perfect leader for an autonomous
hunter-killer unit. Benjamin Church employed ranging tactics to conduct
a variety of offensive strikes against enemy safe havens. Benjamin Church
took the ranging concept to the next level, employing his Rangers deep
into enemy territory for long periods (over weeks of time) with the express
mission of destroying the hostiles and their safe haven support system. The
Rangers fought by copying the style of Indian forest fighting and swamp-
fighting tactics.
Church’s unit almost single-handedly turned around the war effort with
a string of successes against the hostiles. His unit accounted for the death of
King Philip; the capture of Philip’s supporter, Annawon; and a devastating
winter raid (conducted as a combined operation with other colonial militia
units on 19 December 1675) against a fortified camp of Narragansett near
present-day South Kingston, Rhode Island. Dubbed the Great Swamp Fight,
this action eliminated any further serious involvement of the Narragansett
Indians during the remainder of the war.
Benjamin Church used mixed militia and indigenous forces to his advan-
tage along with the frontiersmen knowledge of the outdoors, adoption of
Indian skulking tactics, and well-armed units to overmatch his adversaries.
He adapted to the enemy by learning the intricacies of swamp warfare in
order to expand his operations into that safe haven. His disadvantages were
limited mobility (same as his adversary—foot) and lack of means to sustain
his forces during bad weather.

Church derived early principles from his warfare exploits utilizing
hunter-killer methodologies. His written experiences in hunter-killer types
of operations were passed on and incorporated into the style of ranging
and hunter-killer operations made famous by Robert Rogers during the
French and Indian War. Although Rogers’ exploits form the lore of modern
Ranger history, Benjamin Church should rightly have the title of the father
of the first American military operations employing Rangers as unorthodox
military.
French and Indian War, Rogers’ Rangers. Major Robert Rogers began his
ranging career as a 14-year-old Indian fighter and went on to become the
most famous, although certainly not the first, Ranger of the American fron-
tier. Rogers perfected the art of offensive ranging with his hunter-killer units
by conducting deep penetration raids and reconnaissance missions for the
British forces stationed along the upper state waterways of New York during
the French and Indian Wars. Rogers capitalized on integrating indigenous
forces into his units. They served as scouts, knowing the land well. He raised

volunteers who were physically hardy and superb outdoorsmen, and adopted
unorthodox fighting techniques similar to the hostile Indians. With these
units he led missions into enemy territory—harassing French and Indian
lines, gathering intelligence, and capturing prisoners.
His most notable hunter-killer type operation was the raid against the
Abneki village on 4 October 1759, located at St. François in the St. Lawrence
River valley. Traveling over 150 miles with 142 Rangers and indigenous
Indian irregulars, the village was ruthlessly attacked. Many of the Abnecki
warriors and noncombatants were killed or scattered, and then the whole
village was burned.15
Rogers would go on to command a Ranger contingent during the Revo-
lutionary War, unfortunately on the side of the British. He is most remem-
bered for his Rules for Ranging, promulgated as a result of his experiences.
Rogers’ expedition typified the first derived and applied principles of hunter-
killer and ranging operations to ensure success. His men were handpicked,
including the Mohican scouts. The rangers wore sturdy, frontier clothing
to protect them from the elements and to blend in with indigenous popula-
tions found in his operating area. The Rangers were armed well enough to
match or overmatch their adversaries. Weapons skill and care of weapons
were enforced constantly.
The Rangers traveled fast and light (carrying extra moccasins for long-
range patrols) and often used canoes or boats to increase their mobility.
During winter, skates were used to rapidly transit frozen lakes and rivers,
and snowshoes were used to negotiate the effects of snow on the trails.
Combined with a cultural and geographical knowledge of their area of oper-
ations and the ability to live off the land and travel long distances behind
enemy lines, the Rangers became the most effective, specialized force in
the northeast.
Conversely, the failing attribute of Rogers’ operational style was that he
was not constrained by rules of engagement when conducting his opera-
tions against combatants and noncombatants alike; if prisoners impeded
his movement, they were usually killed. Noncombatants were killed along
with warriors. This tactic was scorned by the conventional British Army
regulars, and Rogers was later rebuked for this operation. The British had
made great propaganda against the French when they employed these tactics
with their Indian irregulars; the high moral ground was lost and the French
continued to allow their indigenous allies to commit atrocities.

Operational Maneuver, Strategic Effect: The Battle of Kings Mountain
1780. There are very few examples of early American military operations
involving hunter-killer teams in achieving a strategic effect based on the
operational maneuver of its irregular forces; most hunter-killer operations
are tactical engagements. This effect might only be accomplished if the
hunter-killer operations are employed as the main element of a war-of-
exhaustion strategy; by the prolonged operations of hunter-killer teams to
wear down enemy insurgents; or the insurgent force is so decimated that
victory is achieved.
The Battle of Kings Mountain in 1780 pitted the irregular forces of the
back-country colonists—the Overmountain Men from Tennessee and militia
from the western districts in North Carolina—against the proxy, provincial
irregular forces of Loyalists commanded by Major Patrick Ferguson.16
After stalemate in the North against Washington’s forces during the
Revolutionary War, British strategy shifted to reliance on a perceived loyal
Tory population in the southern states to defeat the Americans. The English
war cabinet, in consort with its generals, believed it would be possible to
subdue the rebels in North Carolina, South Carolina, and Georgia using
irregulars provided from the Loyalists. After the attack on Savannah, British
forces overran Georgia, and then captured Charleston on 12 May 1780. From
this position of strength, British forces spread military detachments to the
countryside to consolidate their gains. In response, the American General
Gates reacted in August of that year—maneuvering with the Continental
forces at Camden, South Carolina—and was heavily defeated. With the
absence of an American Army to thwart British gains, American patriots
turned to partisan and guerrilla warfare operations to continually harass
the British.
Ferguson commanded a large, irregular force of about 1,100 Loyalists
(which included Rangers). He was ordered by the British command into
western South Carolina (to the fort named “96,” a star, earthen-work fortifi-
cation guarding a trade route), prepositioned to continue operations against
American Partisans in North Carolina. He soon moved his forces north,
scattering the Partisans in his wake, with the intention of linking up with
British forces in Charlotte. Ferguson believed the back country area would
provide him with a loyal populace, provisions, and terrain to support his
maneuver—safe haven characteristics.

41.

JSOU Report 10-1
In response, militia commanders Colonels Isaac Shelby and John Sevier
mustered the largest hunter-killer operation in early American history at
Sycamore Shoals (near modern Elizabethton, Tennessee) on 22 September
1780. With the addition of 200 Virginians under Colonels William and
Arthur Campbell, the force of militia and irregulars let loose from the Shelv-
ing Rock rendezvous point as a flying column to search out and destroy
Ferguson. The column split at Catawba in order to gather more Partisans
and grew to approximately 1,400 men (later dubbed in folklore as the “Ghost
Legion”).
Ferguson soon had word from local spies of this irregular force hunting
for him and stopped at Kings Mountain to gather more reinforcements.
Kings Mountain was a poor choice for a defensive position being isolated
and with very little water. Unbeknownst to Ferguson, none of his messages
calling for reinforcements were getting past the hostile population.
The American hunter-killer force slowed to the pace of its foot soldiers.
In frustration at the pace of movement, the force was reorganized into a
mounted column, leaving the foot soldiers at Cowpens, and pushed ahead
to Kings Mountain with about 900 horsemen on 6 October. Local Tories
captured along the way provided intelligence, and much of the population
provided provisions for the force as it pushed forward (to include the draw-
ing of maps).
Ferguson was soon surrounded. The Americans, using Indian tactics,
were repulsed from the top of the mountain several times. Soon, Loyalist
muskets could not compete with the accuracy and killing rate of American
rifles; they were defeated after Ferguson was killed. American losses were
about 30; the Loyalist force of approximately 1,100 was decimated (about
150 killed, commensurate number wounded, and over 800 taken prisoner).
The American victory ensured the British would never operate in force
again across the southern back country. The victory also dampened the
enthusiasm for Loyalist support for England for the remainder of the war—a
strategic victory.17
The attributes of the hunter-killer operation lending to the success of
American irregulars came from their superior firepower (rifle technology
vs. musket), superior mobility on horseback, knowledge of the terrain and
populace, the innate ability of the American irregular to live off the land, the
hardiness of the physical condition of the irregulars, and the reckless, brave,
charismatic and audacious leadership provided by the militia colonels, most

42.

Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
with warfighting experience. The rules of engagement were unrestrictive, but
American irregulars spared the wounded, treated them as best they could,
and moved the hundreds of prisoners to places of captivity. (The rules of
engagement allowed for the abuse and capture of noncombatants given the
American sentiments against the Loyalist factions of the population and
abuses on the British side.) Detractors were the ad hoc, inexperienced level
of the various irregular militia units, who had never conducted coordinated
operations with one another (although this did not limit their effective-
ness when finally forming for battle). Although slowed by the speed of foot
infantry, the hunter-killer force adapted the flying column to horseback and
prevailed in reaching Ferguson’s force before he could maneuver away.
The ranging tradition spread to other states, and a variety of Ranger mili-
tia units continued to conduct hunter-killer operations for the remainder of
the 18th century. After the creation of a standing U.S. Army, most operations
into the irregular’s safe havens and homelands consisted of conventional
military efforts of long-range penetration under the design of a punitive

expedition or as limited long-range patrols (e.g., Indian Wars in the West,
Texas Rangers, and Philippine COIN campaign). During the Civil War, a
variety of colorful units were formed to track down the elusive Confederate
irregulars of Mosby and Quantrill, but these suffered in effectiveness from
being formed ad hoc out of conventional cavalry units, who were not much
better in the tactics, arms, and skills of their counterparts.
The tradition of conventional punitive columns culminated in General
Pershing’s expedition to Mexico in the early 20th century. Although specific,
small-unit hunter-killer operations (e.g., Ranger units) were no longer the
norm, the small-wars era continued after World War I and did at least
continue to provide hunter-killer-like skills and experiences to the U.S.
military as a COIN technique. This would improve American hunter-killer
operations in the future: the use of indigenous forces, increased mobility
platforms to travel further in rougher terrain, modern and over-matching
weaponry, and technology enhancements (the advent of the airplane and
the radio).
World War II and Beyond
World War II irregular warfare experiences did not expand the American
way of war in the realm of COIN techniques, primarily because the U.S. did
not face an Axis insurgent or guerrilla threat. (The U.S. conducted guer-
rilla and partisan warfare against conventional Axis forces.) It was in this
adversary realm of irregular warfare—actually participating as sponsors and
enablers for guerrilla warfare (e.g., Yugoslavia and the Philippines) —where
much of American doctrinal approaches to UW were formed. Either by
necessity as stay behind forces, or through British tutelage under the Special
Operations Executive, Americans performed capably as insurgents and
guerrillas in their own right. Other SOF were created for the purpose of
raiding or for use as elite infantry, influenced by the European military
design of commandos. Unfortunately, the ranging and hunter-killer ethos
of the American infantry would be transformed when Army Rangers were
employed as shock infantry, tactical raiders, and battlefield reconnaissance
assets.
World War II. Several specialized infantry formations were created during
World War II. For the Army, it was the combined U.S.-Canadian 1st Special
Service Forces and the U.S. Army Rangers, neither of which were used to

44.
35
Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
their full potential to conduct hunter-killer operations. In the Pacific, the
U.S. Marine Corps sponsored the formation of the famous raider regiments,
which became renowned for their exploits while conducting raids on Japa-
nese-held islands.
The 1st Special Services Force conducted a series of operations from
Alaska to Italy and finally southern France, but it was used primarily as a
conventional, light-infantry maneuver regiment. The Rangers were misuti-
lized as vanguard, shock-infantry in Italy where they were all but destroyed.
The long-tradition of ranging behind enemy lines could not be accomplished
in the large, conventional and linear battles fought throughout the war in
Europe.
Two contributions to the art of hunter-killer operations against irregular
adversaries did occur, however, as a result of the war:
The first was in technological leaps, which would enable future hunter-a.
killer operations.
The second was in German antipartisan operational experience, whereb.
hunter-killer teams were used both against the Soviet partisans and
against the Partisans in the Balkans.
In technology, long-range naval and aviation assets now provided plat-
forms for insertion of hunter-killer teams deep into enemy territory, as
well as their extraction. Supplies allowing hunter-killer teams to remain
behind the lines could now be parachute delivered or delivered over the
shore by stealthy submarines and small water craft. The off-road, all-terrain
capabilities of motorized vehicles also enabled hunter-killer teams to navi-
gate in previously inaccessible areas. Efficient and smaller machine guns,
mortars, and antitank weapons ensured future hunter-killer teams could
take on irregulars with staying power, precluding the need for extraction or
rescue by larger forces. But it was the long-range radio that by far enabled
specialized forces to remain much longer in enemy territory. No longer
were mobile or flying columns limited to what they could carry; with the
radio, a reach-back capability existed to call for more forces, weapons, or
logistics as the situation demanded. With the radio also came access to
higher intelligence on the activities of adversaries as well as a capability to
achieve effective and coordinated operations with larger conventional forces
conducting antiguerrilla operations.

45.
36
JSOU Report 10-1
The second contribution for future hunter-killer operations was a result
of extensive study by the U.S. Army of German antiguerrilla techniques to
learn and synthesize military requirements for counterguerrilla doctrine:
Inspired by the German Army’s World War II jagdkommando anti-
partisan doctrine, the U.S. Army’s 1951 FM 31-20, Operations Against
Guerrilla Forces, prescribed the organization, training, and functions
for a prototypical indigenous counterguerrilla unit of platoon size.
Intended to operate independently for prolonged periods, specialized
antiguerrilla units were to be armed with light automatic weapons
and radios for night operations such as raids and ambushes. This
manual also recommended that antiguerrilla units should consider
masquerading as guerrillas to deceive irregular adversaries.18
Earlier German experiences with antipartisan measures were based on
the requirement to protect rear area assets from partisan sabotage attacks
and were primarily designed as limited tactical operations of small-unit
patrolling as a defensive measure. As partisan activities grew from small
attacks by disaggregate bands to heavier, well-organized attacks by compa-
nies and battalions, new measures were needed. The German high command
issued a directive for all units to build hunter-killer teams, jagdkommandos,
with enough firepower and endurance to move into guerrilla areas and
destroy them. Partisans operating against the German forces, like all smart
guerrillas, avoided set piece battles and were extremely adept at eluding
German forces’ attempts to surround them; their intimate knowledge of
the battlefield allowed them to escape into rough terrain or melt into the
population, time after time.
As in earlier French and British colonial experience against irregulars,
German forces adopted the use of mobile columns to penetrate into guerrilla-
held territory. Mobile, heavily armed, and operating at the company size,
German jagdkommandos consisted of specially trained forces, drawn from
existing manpower of elite units who eschewed the need for a long logistics
tail (they lived off the land) and often dressed and equipped themselves to
look like the very guerrillas they were attempting to destroy. The jagdkom-
mandos also used indigenous personnel as scouts and guides and included
in their ranks soldiers who could speak local languages and dialects.
The primary role for the jagdkommando was to seek out and destroy
guerrilla bases. These units by 1943 became very effective at offensive

46.
37
Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
antiguerrilla operations, particularly in the Balkans. The German army
even created an antipartisan badge, the highest award in gold, which became
competitively sought after by members of these organizations. In his book,
Hold the Balkans, Robert M. Kennedy briefly described their role:
A highly effective offensive weapon was found in the Jagdkommando
(ranger detachment), designed to seek out and destroy guerrilla
bands. Personnel of the detachments were usually young and combat-
wise veterans of German campaigns on other fronts. Physically hardy
and trained to live in the open for extended periods of time, they
depended little on supply columns and could pursue the guerrillas,
often burdened down with wounded, families, and impedimenta, into
the most inaccessible areas. When the situation required, the rangers
would put on civilian clothing, disguising themselves as Chetniks
or Partisans, to work their way closer to their wary enemy. In the
event they came upon major guerrilla forces, the ranger detachments,
seldom more than a company in strength, would keep them under
observation and inform battalion or higher headquarters. While
awaiting reinforcements, they would attempt to gather additional
information on the guerrilla strength and dispositions. As success-
ful as they were in many small-scale operations, however, the ranger
detachments were not numerous enough to affect decisively the
outcome of the antiguerrilla campaign.19
Advantageous lessons learned were in the need for mobility to outma-
neuver the partisans, how to overmatch their firepower, how to effectively
blend with the insurgents through altered appearances, and using locals
for intelligence. Airpower increased the longevity of the force by provid-
ing resupply, close air support, and MEDEVAC. Decentralized command
and missions of broad scope were the norm. The jagdkommando concept
distracter was common to totalitarian militaries: loose rules of engagement
resulted in brutality and repression of noncombatants as well as severe treat-
ment for captured insurgents. These activities nullified local population
support for the Germans.
Post-World War II Era. After World War II the American military had
limited experiences in COIN for promulgating doctrinal approaches to
counterguerrilla and counter safe haven methodologies, specifically hunter-

47.
38
JSOU Report 10-1
killer employment. For operational art on the subject, they were mostly
reliant on the experiences of other nations. The post-World War II irregular
warfare era was characterized by revolutionary, anticolonialist national
movements, and communist people’s war. U.S. knowledge of COIN tech-
niques under these types of war was gleaned from British and French COIN
operational art—now changed in character with the advent of a new tech-
nology: increased mobility via helicopters.
In the Korean War, Americans once again faced no threat from Chinese
or North Korean guerrillas to a sufficient extent; thus, they had little impetus
to further refine and develop U.S. COIN techniques, preferring to conduct
specialized operations much like their World War II experiences—employ-
ing unconventional forces as guerrillas and espionage operatives against
the enemy. While they could have developed skills relevant to hunter-killer
operations, Rangers were once again used predominantly as light infantry,
mostly as tactical reconnaissance units, capable of small raids, and deep
battlefield scouting units (intelligence gathering) under the Army Corps
structure.
The U.S. involvement to assist Greece against their internal communist
insurgency immediately after World War II could have furthered evolve-
ment of U.S. COIN doctrine, but in the mainstream was security assistance,
within the parameters of a host-nation IDAD plan. No major COIN forces
were deployed during this advisory effort. The American military would
not conduct hunter-killer type operations until its involvement in the Viet-
nam War.
Vietnam War. The American way of war in COIN was heavily influenced
by its involvement in the Vietnam War, challenging the doctrinal approach
to fighting irregular warfare adversaries at a scale not seen in American
military history. Every possible approach to fighting irregulars and a main-
stream, revolutionary people’s army was attempted during the conflict. The
Vietnam War was also the impetus for transcending the nature of how the
American military viewed special operations. The SOF heritage is a long
historical one of ad hoc experiences gained throughout the nation’s wars,
but today’s SOF owes much of its operating style and mission sets to World
War II and the Vietnam War, defining the strategic utility of SOF, and to
the relevance of its tactical operations in achieving operational goals and
objectives.

48.
39
Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
In World War II, the U.S. military came away with some limited expe-
rience in UW, commando-style raiding techniques, and guerrilla warfare.
In Vietnam, specialized warfare grew to include unique COIN skills for
FID, prisoner of war rescue, long-range and strategic reconnaissance, direct
action with specialized assets, and foreign advisory and assistance skills.
Without a doubt the most transcendent act was the creation of Green Berets
(the Army Special Forces) in the early 1950s, later supported by President
Kennedy as a means to answer irregular adversaries with America’s own
version of guerrillas.
In Vietnam, hunter-killer techniques were adopted by both the conven-
tional Army and within the Army Special Forces. Although having a long
tradition of historical use of Rangers to conduct ranging operations deep
into enemy territory in the early colonial era, the Rangers once again were
used in the role of long-range reconnaissance assets to support conventional
unit tactical intelligence-gathering operations (similar to their role in World
War II). Other specialized units, like the Special Operations Group (SOG)
formations, again found roles in conducting strategic reconnaissance opera-
tions deep into enemy territory as their primary mission. This is not to say
that Ranger operations and SOG operations did not achieve effects desired
in creating mayhem in enemy-held territory while contributing to counter-
organization successes. It is rather to highlight that they were specifically
formed as intelligence-gathering and reconnaissance assets, not hunter-
killer units for long-duration operations in enemy safe havens.
Of the attempts to employ hunter-killer teams, two are noted here:
one was the U.S. Army retailoring its conventional infantry, and the other
was Special Forces specifically mission-purposed. The conventional forces
attempt to employ hunter-killer teams in the Vietnam War COIN environ-
ment illustrates a lesson not learned in the Army’s earlier attempts to employ
hunter-killer teams during the Civil War: the failure rate when adapting
conventional formations to this requirement was high.
In November 1965, the then Major David Hackworth was instrumental
in creating an organization, guerrilla-like in nature, to fight the Viet Cong. It
was a derived, personal philosophy based on his wartime experience. Within
the 101st Division, the new Tiger Force hunter-killer concept was adopted
to create platoon-sized units from hand-picked soldiers across the divi-
sion. One became a hunter killer, based on attributes gleaned in command
interviews: months of combat experience, psychological propensity to have

49.
40
JSOU Report 10-1
hunter-killer instincts, and of course, audacity. Once picked, the soldier
joined the elite Tiger Force and was issued a set of tiger-striped fatigues to
distinguish him from normal infantry units.
The Tiger Force units conducted small-unit actions and were designed to
operate in the field for weeks and take the fight into the jungle to hunt and
kill Viet Cong, based on the member’s ability to conduct effective jungle
warfare. During population resource and control operations, the Tiger
mission was to look for Viet Cong and food caches, then destroy them. The
Tiger Force hunter-killer concept was used throughout 1967 in operations
near Dak To, Duc Pho, and Chu Lai, in the Central Highlands campaign.
Most of the Tiger Force became reconnaissance platoons at the brigade
level and never achieved the goal of conducting deep, long-duration opera-
tions against the enemy. Nor were they afforded the assets or independent
authorities required to be effective hunter killers.
Over a period of time the units were looked on with distrust. Senior
officers felt their operations caused too many friendly casualties (they were
almost wiped out in June 1966 while pursuing North Vietnamese Army
main-force regiments), and the unit was soon accused of committing atroci-
ties during their operations. The unit was disbanded after claiming almost
300 enemy kills, some of a suspect nature.
Although adopting enemy tactics, selecting hand-picked personnel, and
providing aggressive and audacious leadership, the concept failed from
lack of discipline, hierarchal command and control mechanisms, and little
autonomy to conduct effective operations. The unit was ad hoc in form-
ing and was an attempt to convert conventional infantry into specialized
irregulars.
The use of an organized hunter-killer formation came with the forma-
tion of the Mobile Guerrilla Force trained and led by U.S. Army Special
Forces for the purpose of complementing indigenous Vietnamese tribal
mobile strike force units (MIKE Force). Responding to the need for quick
reaction forces for the various U.S. Special Forces base camps involved in
the Civilian Irregular Defense Group (CIDG) program, Green Berets soon
became adept at conducting counterguerrilla operations with indigenous
forces who were not placed under the control of the South Vietnamese
Army—in essence, their own autonomous maneuver force. Unfortunately,
this autonomy also created isolation and distrust from conventional units

50.
41
Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
when it came time to seek their reinforcement during battle. (To resolve
the issue, the Green Berets created the mobile strike formations to quickly
back up beleaguered CIDG outposts.) Taking the concept one step further,
the Green Berets realized sitting in base camps awaiting enemy attack was
not a creative use of indigenous forces. To become more offensive in nature,
the Green Berets created company-sized Mobile Guerrilla Forces to take the
fight to the enemy in his sanctuaries and safe havens. Thus the first, and
maybe the only, professional hunter-killer unit in Vietnam was created.
The Mobile Guerrilla Force concept was developed in late 1966 by Colo-
nel Francis J. Kelly. He envisioned his concept as forming COIN hunter-
killer teams using clandestine counterguerrilla techniques to infiltrate
into guerrilla areas of operation for the purpose of engaging enemy forces,
destroying their logistics, interdicting their lines of communication, and
creating a psychological climate of fear within the enemy’s mind as to his
safety while operating within his base areas. This action would also force
the enemy to defend his bases and logistical centers, allowing the hunter
killers to control the pace and tempo of the operation. These company-sized
units were intended to conduct 30-to-60-day operations and were led by a
U.S. Special Forces team.20
The creation of the Mobile Guerrilla Force in October 1966 provided an
active measure to seek out and destroy Viet Cong and North Vietnamese
Army (NVA) regulars enjoying safe haven and sanctuary in the III Corps
Tactical Zone. Named War Zone D, (and the Forbidden Zone by the enemy)
this territory was used by Viet Cong and NVA forces to establish base camps
and logistics areas within South Vietnam at the terminus of the Ho Chi
Minh trail; since this area was almost devoid of friendly force control, the
enemy could preposition and prepare for further attacks into South Viet-
nam. Without sufficient American and South Vietnamese forces to counter
this buildup, the concept to employ U.S. Army Special Forces and their
indigenous assets from static base camps (along with light counterguerrilla
security patrolling) into a guerrilla force easily won favor with General
Westmoreland.
Initially, Cambodian CIDG soldiers of Khmer Serei ethnicity were
recruited to form the company under the command of Captain James “Bo”
Gritz. In his first meeting on the concept, Colonel Kelly described what he
desired:

51.
42
JSOU Report 10-1
… a company-sized force capable of conducting guerrilla operations
in War Zone D for periods ranging from 30 to 60 days. This light
infantry company would have to operate without artillery support or
chance of reinforcement. The unit’s sole support would consist of a
single forward air control aircraft, tactical air strikes, and parachute
drops of food, supplies, and ammunition every 4 days.21
The Mobile Guerrilla Force consisted of about 160 to 170 men, orga-
nized into a headquarters platoon, reconnaissance platoon, and three or
four maneuver platoons, depending on the tactical operation. The force was
equipped with the standard U.S. equipment for weaponry and radios. After
initial training at the Ho Ngoc Tao Special Forces camp (home of project
SIGMA—Special Forces and indigenous long-range Corps reconnaissance
teams), the ready company deployed to the Special Forces camp at Duc
Phong to begin missions in War Zone D.
The Mobile Guerrilla Force conducted numerous operations in War
Zone D against the Viet Cong 9th Division and other NVA main force regi-
ments. These missions were labeled “Blackjack” (Colonel Kelly’s nickname)
followed by a two-number designation denoting the Corps, then the mission

of gunships, provided the long-range interdiction and close air sup-
port fires for teams operating without artillery support at long distances
within enemy safe havens and base areas.

sequence (e.g., Blackjack 31 and Blackjack 32). Their missions focused on
the destruction of the enemy forces, his base camps, and enemy logistics
throughout the zone while also providing updated intelligence to the 1st
Infantry Division and other friendly conventional forces.
The employment of the Mobile Guerrilla Force lasted until late 1967 when
the unit’s manpower was rolled into the larger mobile strike force units
and the reconnaissance projects SIGMA and OMEGA. The Mobile Guer-
rilla Force project represented one of the American military’s best attempts
to employ hunter-killer teams in a COIN environment. It also served as a
model for the contemporary evolution of COIN hunter-killer teams. The
doctrine from these hunter-killer operations, combined with increasing
levels of modern transport and technology to enhance these operations,
would form the basis of future success by SOF hunter-killer teams when
Operation Enduring Freedom changed from a guerrilla warfare scenario
into a COIN effort.
The guarantee of the Mobile Guerrilla Force success in hunter-killer oper-
ations was in adhering to the following principles of their employment:
Use of indigenous anda. SOF small units as a purpose-built organization
Knowledge of the terrainb.
The role unconventional and audacious leadership plays in the usec.
of the hunter-killer team
Increased mobility with the use of helicoptersd.
Wide latitude to conduct independent operationse.
Modern resupply methods and a logistic system to support the unitf.

A supportive quick reaction force to reinforce beleaguered units.h.
Conversely, this COIN hunter-killer concept suffered the historical fate of
different units—not enough of them, not everywhere, and not long enough—
to have made an appreciable difference at the operational level of war.
Post-Vietnam War, the 1980s and 1990s. Although the post-Vietnam War
period was rife with insurgencies around the world, the American military
distanced itself from any future entanglements in COIN environments,
losing much of the operational art and COIN acumen amassed from the
Vietnam War. As the conventional military repaired and rebuilt itself to

53.
44
JSOU Report 10-1
once again handle the major war spectrum, much of the necessary skills
needed to fight in irregular warfare devolved to the special operations
community.
Soon a more imposing threat entered the world scene: terrorism. To
remain viable, special operations began a narrow focus of mission sets to
conduct counterterrorism operations. However, with few deployments into
this irregular warfare playing field as a result of political constraint and
public reluctance, Special Forces returned to FID and security assistance
activities. This shift reinforced a notion amongst Green Berets that if you
cannot fight wars, get involved in teaching other people how to fight wars
in order to sustain your skills.
While a few brush wars occurred during this period (e.g., Grenada and
Panama) along with the major conventional war Operation Desert Shield/
Desert Storm, America was not challenged with an irregular warfare adver-
sary requiring the employment of U.S. forces to conduct COIN mission
sets. At best, U.S. Army Special Forces trainers were able to maintain COIN
hunter-killer knowledge when used as advisors in Venezuela, specifically
in the training of cazadores (hunter-killer) battalions and training hunter-
killer battalions in the El Salvadoran Army.
One other initiative during this period, although not originally conceived
as a hunter-killer concept, was more than prescient in ensuring America
would have purpose-built hunter-killer teams when the need eventually
arose. In 1984, Colonel James Guest—commander of the 5th Special Forces
Group (Airborne)—hereinafter referred to as “the Group”—transferred an
experimental Special Forces company known as B-500 to Fort Bliss, Texas
to develop the tactics, equipment, and operating principles for a desert,
long-range, and mobile Special Forces capability.
B-500, Purpose-Built Hunter-Killer Team. B-500 was established in the
early 1980s by Colonel Guest to address the needs and requirements of the
Group for conducting desert warfare in accordance with their war plans in
the United States Central Command (USCENTCOM) region. The overall
program for execution was named the Desert Mobility System, comprised
of weapons, soldier equipment, and mobility platforms (to include high
altitude parachutes) needed by the Special Forces soldiers for conducting
long-range, long-duration missions in a desert environment. In essence,
B-500 was a test-bed unit for the Group.

54.
45
Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
The mobility platform requirement was based on future combat scenar-
ios, which required the Group to conduct a variety of missions involving
extreme infiltration/exfiltration ranges. The desire for a vehicular infiltration
method was based on the shortage of airlift and special operations aviation
assets at the time, which could effectively hamper the employment of the
Group assets in a major war. Thus the parameter for 500 miles in and 500
miles out without resupply (and be able to operate up to 10 days) became
the standard for a vehicular-mounted Green Beret team (the Special Forces
Operational Detachment–Alpha, the “ODA”).

Test a variety of weapons, communication gear, personal clothingc.
and tentage, parachutes, and so on for their usefulness to conduct
operations in a desert environment under extended duration.
The unit discarded the previous mobility platforms of one-quarter ton
jeeps for modified M880 trucks and added homemade trailers to carry the
logistics and motorcycles required to conduct long-range desert operations.
Later the unit adopted the Army HMMWV variant as the preferred mobility
platform and conducted a series of 1,000-mile missions to gain experience.
These early trips provided an abundance of lessons learned for mounted
movement, and the unit wrote its first mounted handbook to pass on for
use to other members of the Group. Along with the vehicle tests, the unit
also experimented for the first time with satellite communications and navi-
gation (SATCOM and SATNAV) systems. The Mk-19 and the .50-caliber
machine gun were also used in testing.
As a result of the positive feedback from team members, the HMMWV
was chosen as the vehicle of choice for mounted teams. Initially each team
was equipped with two M1025s (clamshell with ring mount and winch) and
two M998s (cargo version). During the testing period a great partnership
and association with the border patrol developed, and the border patrol
transferred some trucks and about 15 dirt bikes (350cc) to the unit (these
were contraband seized from drug raids and considered federal property).
When the entire Group was relocated to Fort Campbell, Kentucky the
B-500 unit reverted back to A Company, 1/5th and returned home to the
Group. Much of what B-500 accomplished would contribute to Special
Forces hunter-killer capability after 9/11 as a force in being.
Operation Enduring Freedom. In the summer of 2002, the reemergence of
the Taliban as insurgents dictated a COIN response from allied and coalition
forces. However, the expected war with Iraq meant continuing operations
in Afghanistan would be as an economy of force, which ceded vast portions
of Afghan rural areas to the insurgents. Afghan security forces were scarce.
Counterguerrilla techniques used by the coalition were limited to close
proximity security patrolling; occupation of key, forward-operating bases
to maintain a presence; and battalion sweep operations conducted by the
various allied and U.S. conventional infantry forces. The predominance of
SOF assets, both U.S. and coalition, focused on counterorganization missions
to hunt down remaining Al Qaeda and senior Taliban leadership while

56.

simultaneously utilizing indigenous security forces to protect key pockets
of the population and interdict enemy efforts.
While hunter-killer concepts cannot work in isolation from the myriad
of counterguerrilla techniques used by COIN forces, this situation provided
the exact environment for the employment of U.S. Special Forces mounted
teams to conduct hunter-killer missions as part of the effort to erode and
exhaust the Taliban during 2002 and after.
U.S. and coalition SOF, particularly those units with self-contained
mobility and firepower, were used on a variety of missions to roam in semi-
permissive and nonpermissive areas of Afghanistan. The purpose was to
harass the enemy or find, fix and destroy the enemy either with organic
firepower and close air support or in conjunction with larger conventional
reaction forces.
Based on intelligence, local information, and terrain analysis, Special
Forces mounted teams were employed across vast areas of “gridded” terrain
to ascertain enemy activities and strength within each grid. If successful,
enemy caches were destroyed, enemy safe houses cleared, and sanctuary
areas (safe havens) were put at risk for Taliban occupation. Most clashes with
Taliban forces were successful in eliminating or capturing enemy fighters.
Hunter-killer teams remained highly mobile with organically tailored
vehicles. All patrols were designed for long-range operations in suspected
enemy territory, and although scarce resources in helicopters for these
unique operations could have limited the duration of hunter-killer team
deployment, a system of bundle and cargo drops for resupply guaranteed
increased time of the teams in the field. Mission durations ranged from a
couple of weeks to a 6-week operation by a coalition SOF contingent. Close
air support (CAS), either with fixed-wing or rotary-wing assets, provided
long-range, heavy firepower because artillery was not prevalent in the first
years of the COIN period. Maneuvering with all terrain, heavy bed vehi-
cles afforded increased weapons platforms (.50-caliber, light machine gun,
AT-4s, and MK-19 grenade launchers) to give the hunter-killer team’s fire-
power overmatch against the Taliban.
Just as in the Vietnam Mobile Guerrilla Force concept, hunter-killer
teams were optimized with indigenous, irregular forces in company
strength. Their vast knowledge of tribal affairs, local language, combined
with their intimate knowledge of the terrain, contributed to the overall
success of many of these patrols.

JSOU Report 10-1
An operation in one of the central provinces during the summer of
2003 illustrated the effectiveness of the hunter-killer concept. During their
earlier war with the Soviets, the Afghan mujahideen made much use of the
mountain ranges near Kandahar as an inner safe haven and stronghold
to train, recruit, resupply, and refit. This area is comprised of harsh, high
desert mountains with very narrow valleys and small, isolated villages. A
variety of indicators by the late summer of 2003 showed that the Taliban
were regrouping in this area by the hundreds, presumably to affect the
upcoming fall elections scheduled throughout Afghanistan.
The Combined Joint Special Operations Task Force - Afghanistan directed
coalition and U.S. hunter-killer teams to conduct a probe into the area in
order to ascertain the extent of the Taliban’s activity. After one contact
between a coalition SOF patrol and suspected guerrilla force occurred,
a robust U.S. Special Forces hunter-killer unit was deployed along with
approximately 150 irregular forces provided by the governor of Kandahar,

mobility vehicle (modified HMMWV) to conduct long-duration and long-
range counter safe haven and interdiction operations against Taliban forces

in anticipation of combat operations. As they drove deeper and deeper into
the mountain sanctuary, many of the villagers warned them of a large pres-
ence of enemy. Contact soon occurred by enemy ambush, which surprisingly
was professionally executed by the Taliban and included the use of mortars
and snipers.
Three days of fighting ensued; the hunter-killer unit was reinforced by
a Quick Reaction Force from the Kandahar-based Special Forces battalion,
while conventional forces readied for insertion to create a classic hammer-
and-anvil maneuver. As the fight progressed, hundreds of Taliban were
either killed or captured as air support assets were added to the battle.
Sensing defeat, the remaining Taliban elements attempted to exfiltrate the
area, but most were destroyed in continued engagements by AC-130 aircraft.
Estimates of enemy strength hovered around 500 insurgents. The enemy
was defeated, the sanctuary denied, and the fall elections were successfully
conducted without the interference of the Taliban. It serves as one of the
21st century’s most successful hunter-killer operations on the part of U.S.
forces to date.
This overall achievement was due to operating within the principles of
hunter-killer operations, employing special purpose units, and leveraging
both technological enablers and the use of local, irregular forces in a COIN
environment. The hunter-killer unit was a standing organization, specially
trained for the task. The ground commander enjoyed broad scope in the
mission to conduct autonomous operations. As the battle grew, firepower
overmatch was achieved. Resupply was immediate via rotary-wing assets
or fixed-wing bundle drops.
Summary
While U.S. forces also fought irregulars and insurgents in Iraq, that insur-
gency is predominantly urban in nature and requires manhunting and
counterorganization skills to counter the enemy. Few situations during the
war in Iraq have afforded American forces the need to conduct hunter-killer
operations into enemy safe havens on the scale as they have in Afghanistan
(although the isolation, containment, and reduction of enemy forces in the
Fallujah urban safe haven provide valuable lessons).
Whether in the horse-and-musket period or in the period of contempo-
rary irregular wars, hunter-killer operations are one of the options to present
the enemy a series of dilemmas during counterguerrilla operations. As is

59.
50

evident in the historical experiences, Americans have effectively employed
some form of hunter-killer operations when faced with irregular warfare
adversaries. From this body of knowledge we can derive unifying themes
and principles for doctrinal adoption.

Principles of Hunter-Killer Team Employment5.
during Counter Safe Haven Operations
Whenever you are ordered out to the enemy forts or frontiers for
discoveries, if your number be small, march in a single file, keep-
ing at such a distance from each other as to prevent one shot from
killing two men, sending one man or more forward and the like
on each side at the distance of 20 yards from the main body, if the
ground you march over will admit of it, to give the signal to the
officer of the approach of an enemy, and of their number....22
— Robert Rogers’ Rules or Plan of Discipline
In principle, hunter-killer operations afford sound tactics to create havoc
against irregular warfare adversaries by operating in their space for
sabotaging and destroying their war-making assets and killing their
action arms—the guerrilla forces and auxiliary forces—in order to create
a loss of enemy combatants, lowering of morale, and sowing of dissension
and weariness. Counter safe haven hunter-killer operations are conducted
by small unit, specialized organizations who adopt the enemy’s style and
tactics in order to operate as effective counter-guerrillas. In that respect, U.S.
hunter-killer teams allow the COIN forces to deny the enemy the chance to
continue protracting the conflict.
Hunter-killer operations are one of the active measures in COIN to attack
enemy organizations as part of the war of exhaustion and contribute to the
attrition of enemy combat power. A byproduct of hunter-killer operations is
first-hand information and intelligence-gathering capability while operating
in enemy territory.
Hunter-killer operations can vary in length, area of operations, and by
type unit conducting hunter-killer activities against irregulars, but its main
operating principle is its purpose and aim: attrition of the irregular warfare
enemy. This requires a second operating principle to be considered for any
COIN-derived hunter-killer operation: they are conducted by penetrating
insurgent safe haven space, whether the space is denied or semipermissive
territory.
Hunter-killer operations have been conducted in combination with puni-
tive expeditions, but if employed in this manner, can quickly degrade into

61.
52
JSOU Report 10-1
using the hunter-killer force for security of flanks or for the conduct of
reconnaissance missions for the larger conventional force. General Persh-
ing’s expedition into Mexico against Pancho Villa’s irregulars illustrates
this approach.
Hunter-killer forces should never be formed as a result of converting
conventional infantry forces, as the historical examples from the Civil War
and the Vietnam War illustrated. Hunter-killer forces are not line infantry
nor shock or raiding infantry. Rather they are uniquely tailored special
infantry. Specialized infantry formed as hunter-killer units generally cannot
achieve decisive blows, tactically or operationally, when employed for short
duration raiding purposes. They are also not pseudo-organizations, nor
counterorganization units, although effects achieved in these two types of
operations can be a byproduct of hunter-killer employment. More impor-
tant, however, hunter-killer operations should contribute to the attainment
of strategic and operational objectives.
Additional principles of employment derived from the historical analysis
of the use of hunter-killer operations by the American military are helpful
to review for formulating doctrine and include:
Environmenta. . Hunter-killer teams are best employed during irregular
warfare environments where the adversary confronting the U.S. and
its allies consists of insurgent forces of sufficient size to field a guerrilla
action arm, a supporting auxiliary, and a perceived safe haven for sanc-
tuary believed to be free of friendly forces. The ground commander
has made the conscious decision to conduct territorial offense type
operations for achieving desired counter safe haven effects.
Command and controlb. . Hunter-killer operations require independent
maneuver in enemy territory; measures to deconflict fratricide issues
are paramount when they are ongoing friendly operations. Graphic
control measures, such as unconventional warfare operational areas
(UWOAs), and Blue Force tracker technology will assist in limiting
fratricide. Consideration should be given to the creation of free-fire
zones or forbidden zones in order to increase the flexibility of the
hunter-killer force. Unique passage-of-lines techniques are required
if the hunter-killer force resembles enemy insurgents. Tailored rules
of engagement should be considered to give the hunter-killer force
the widest latitude to take on enemy forces. Command and control

62.
53
Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
is flattened and decentralized to the commander of the hunter-killer
force. As an operating concept, hunter-killer forces should be under
the operational control of a special operations headquarters reporting
directly to the joint force commander.
Composition of the hunter-killer forcec. . Hunter-killer forces should
not be formed ad hoc; standing, specialized forces with the inherent
characteristics for conducting hunter-killer operations are requisite for
success in the irregular warfare environment. Hunter-killer organiza-
tions will be one of nontraditional organization and task organized
based on the context of the insurgency and irregular warfare environ-
ment. Care should be taken to ensure the higher command supports
and sponsors its nontraditional employment. Hunter-killer units
should not be organized as commando or raiding forces. In forming
hunter-killer units, a small footprint is desired. Individuals chosen
to man hunter-killer units should be specially selected, self-reliant,
and capable of adaptation to the environment and to the enemy’s
tactics and style. They must be independent in thinking, masters
of the ambush, and have a psychological make-up for operations
that can be ruthless and lethal. Cultural and language skills for the
operational area are highly desired. They must have a natural ability
to work with indigenous forces as part of the organizational structure.
Hunter-killer organizations will be amoeba-like with self-organizing
traits to maintain their adaptability. Due to the high endurance opera-
tions, the force must be in superior physical shape and be skilled in
living off the land.
Irregulars and indigenous forcesd. . Hunter-killer operations can
achieve increased performance when they incorporate indigenous
forces into their organization (as in General Crook’s use of Indian
scouts during his southwestern U.S. campaign against hostile Indians).
This may be through the use of turned enemy combatants (former
adversaries who now work for friendly forces to find insurgents),
informants, local scouts, or larger auxiliary forces. Of most utility
would be the training and equipping of foreign and indigenous hunter-
killer units to enhance partner capability; these forces could even be
employed as partner or proxy paramilitaries when U.S. involvement
is not desired or must be discrete (covert and clandestine).

63.
54
JSOU Report 10-1
Leadershipe. . Leadership above the hunter-killer organization’s level
of command must be highly supportive to ensure the survivability
of an unorthodox and unconventional organization within the U.S.
military structure. Specialized units enjoying a limited amount of
control, wide latitude for independent operations, and a high freedom
of maneuver very often risk the ire of traditional, formal militaries;
they are often perceived as outliers with lack of discipline. Within the
hunter-killer organization, the leadership must be chosen for their
vast knowledge of unconventional operations (understanding of the
employment of unorthodox operations), audacity, and the ability to
be independent and decisive. Leaders must be proven as capable of
conducting innovative and nonconventional tactics. Successful lead-
ers of hunter-killer operations have tended to be highly charismatic
and aggressive.
Specialized trainingf. . Hunter-killer units require specialized training
in enemy tactics and weaponry, long-range endurance operations,
infiltration and exfiltration techniques, and combat techniques most
useful to the irregular warfare fight. Advanced training in subversion
and sabotage techniques, along with how to conduct psychological
action measures, will be required. Because hunter-killer operations
will be extended operations, sufficient cross training of combat skills
is required in order to maximize the skill sets of each person, consid-
ering that personnel replacement opportunities may be limited. All
training should be done to the realistic conditions the hunter-killer
unit may expect to encounter.
Mobilityg. . The hunter-killer force requires equal or superior maneu-
verability and mobility to the enemy in order to succeed. The force
will require speed to outmaneuver the enemy in his territory and if
required, speed to escape any counter attempts to destroy the hunter-
killer force. The highly preferred method is to mount the force in
all-terrain vehicles that allow for increased range, can carry sufficient
supplies for long duration, and provide platforms for additional fire-
power. Aviation mobility is a key hunter-killer enabler; consideration
should be given to a direct support relationship between aviation units
and the hunter-killer unit for matters such as transport, resupply,
medical evacuation, and liaison.

64.
55
Celeski: Hunter-Killer Teams—Attacking Enemy Safe Havens
Firepowerh. . Along with organic firepower, with necessary overmatch
to any known insurgent capability in order to achieve local superiority,
the hunter-killer unit will require the integration of reinforcing fires
if the effects of combat with the enemy begin to severely endanger or
attrit the hunter-killer force. Long-range artillery (although this may
have some limitations at deeper ranges), CAS, or fires from persis-
tent, armed unmanned aerial vehicle/system (UAV/UAS) platforms
are programmed as part of the hunter-killer operation. Larger quick
reaction forces, notably with a raiding capability, form part of the
backup or can reinforce escalation of force as needed during planned
hunter-killer operations.
Technology enablementi. . Hunter-killer units should be provided the
latest in technology to improve their combat performance, endurance,
and force protection. Hunter-killer doctrine for employment should
change as technology changes to maintain the efficacy of the find-
fix-destroy combat template. This will require an equipping process
to take advantage of rapidly emerging technologies. Additionally,
hunter-killer forces should be equipped with the latest sensor/coun-
tersensor capability to expand their operational reach or to allow
them to conduct economy-of-force operations.
Intelligencej. . Hunter-killer operations will require an unusually high
amount of intelligence on the enemy and the geography of the oper-
ating area. Dedicated platforms and intelligence support, combined
with the intelligence-gathering capacity of the hunter-killer opera-
tion, can help to achieve intelligence dominance within insurgent
safe havens.
Sustainmentk. . Hunter-killer operations must be capable of tailored
long-range, long-duration missions, often outside the scope of friendly
lines of communication. Limitations on combat service support must
be factored into the planning. In earlier periods of irregular warfare,
this involved knowledge of living off the land and having the ability
to be self-sustaining (foraging or capturing enemy supplies). While
these efforts are still viable, technology-enabled hunter-killer teams
equipped with mobility platforms will require a logistics system to
support uniquely American gear if the force is not totally equipped
to look like the enemy. Air support is the most important resupply
capability for hunter-killer operations, whether it comes from manned

65.
56
JSOU Report 10-1
or unmanned aerial resupply vehicles. The hunter-killer organiza-
tion will also require innovative funding to conduct operations in
enemy territory (e.g., enemy script, gold, and barter materials) as
well as reliable funding mechanisms to support their organization.
A dedicated maintenance capability for the myriad of small arms,
vehicles, and radios can provide a reach-back capability once the unit
is employed. The hunter-killer organization needs an organic rapid
equipping capability for off-the-shelf items and procurement of the
latest logistics assets to enhance the fight.
These principles capture unifying concepts to provide a framework for
the doctrinal employment of hunter-killer operations. As irregular warfare
operations continue around the world, the experiences and growing knowl-
edge of hunter-killer activities will add to COIN and irregular warfare litera-
ture. For instance, how do we conduct hunter-killer operations on a hybrid
war battlefield? How should we conduct hunter-killer operations in an urban
environment?
The American way of war in irregular warfare includes hunter-killer
operations to varying effect—they are the asymmetric version of search
and destroy behind enemy lines or in their safe havens. It should be a clear
concept embodied in U.S. COIN manuals. However, to date there is little
doctrinal capture of hunter-killer units in COIN doctrine and a correspond-
ing absence of guidelines on how to employ them.

Conclusion6.
But now the need for the other kind of right stuff—the hunter’s
eye and ear—was making itself indispensable…. This was a war
in which everyone realized that enemy headquarters might at any
moment be visited, and not by noisy frontal formations making
themselves heard 10 miles away but by silently delivered, soot-face
marauders or by hunter-killer teams flying out of the sun or step-
ping from suburban hedgerows. Just as the wholesale slaughter of
civilians reasserted itself in war, professional courtesy was breaking
down into a practice of targeting individuals—by ‘band of chosen
and picked young men … sworn to stick together’—that might as
well have come out of Utopia, or at least the Dark Ages.23
— Derek Leebaert, To Dare and To Conquer
All effective COIN and counterterrorism security operations are
an orchestration of offensive and defensive measures to thwart
the insurgent action arm’s or the terrorist organization’s ability to
choose the time and the place of violence against the state. Offensive actions
allow friendly forces to control the operations tempo of the fight, throwing
the insurgent force off balance and preventing the protraction of the conflict.
Offensive actions allow counterinsurgents and counterterrorists the ability
to get inside the enemy’s decision cycle. Offensive actions necessitate plans
that consider denying irregular warfare adversaries their base areas, support
systems, and safe havens and erode or exhaust their will and manpower.
These are enemy strengths, but they also have associated vulnerabilities.
While a variety of defensive counterguerrilla options afford COIN forces
time to neutralize, isolate, contain, or even manage areas ceded to the insur-
gents, the most effective measure is to take the offense to the enemy using
some application of the find-fix-destroy model. Hunter-killer operations are
offensive in nature and one of the means to find, fix, and destroy.
Hunter-killer operations, combined with other counter safe haven
measures, are the most feared by insurgents. Hunter-killer operations invade
insurgent space and destroy the myth of inaccessibility and security. Fight-
ing the enemy on his own turf disrupts his attempts to recover and refit, and
if handled effectively, can isolate supporting populations from the irregular

67.
58
JSOU Report 10-1
warfare adversary. Conducting operations at a friendly time and place of
choosing creates a psychological effect of fear within the insurgents, who
never know if they are safe. Hunter-killer operations also erode and exhaust
the enemy through attrition, raising the contact rate between friendly forces
and the enemy.
Irregular warfare history is consistently illustrative of the employment of
some type of hunter-killer unit to interdict, harass, and track down insur-
gents in their territory. Since the colonial militia era in America, hunter-
killer operations have been included in personal writings, recommended
rules for tactical operations, or in U.S. doctrine, although the exact term
escapes capture. The early military legacy on this subject was formed in
the ranging experiences of independent Ranger companies. The small-wars
period introduced mobile columns, flying columns, punitive expeditionary
columns, and long-duration roving patrols. After World War II, as Ameri-
can experience in contemporary insurgency grew, these counterguerrilla
activities became raids, special operations, unconventional operations, and
interdiction tasks. Finally, in Operation Enduring Freedom, U.S. and coali-
tion SOF once again employed formal hunter-killer operations to find-fix-
destroy Taliban insurgents. These operations were a morphing of ranging
and deep penetration raid techniques.
Employing hunter-killer operations is a doctrinally sound COIN tech-
nique proved by historical experience and also found in some form over the
years within our irregular warfare doctrine, although not in any compre-
hensive manner. The set of unifying principles for hunter-killer operations
derived in this paper may serve as a useful framework to develop future
doctrinal approaches on the employment of hunter-killer teams as a viable
counter safe haven measure.
In 2008 the Joint Chiefs of Staff sponsored a futures war game with a
hybrid war scenario pitting the U.S. and its allies against technologically
enhanced irregulars. One of the options the participants chose to disrupt
enemy space was a form of U.S. hunter-killer teams. It is time to include the
employment of hunter-killer operations into American irregular warfare
doctrine and clearly in the next revision of the COIN field manual.
What would a hunter-killer unit look like? Of course it must be designed
within the context and requirements of the irregular warfare scenario, but
the Figure 6 organizational chart is proposed merely as a point of departure
for further discussion and development, based on the past experiences of

U.S. hunter-killer operations. Inherent in this organization is the organic
mobility platforms of the strike teams to infiltrate, operate for long duration,
and exfiltrate from the operational area. Strike teams include a reconnais-
sance and heavy weapons element. Indigenous forces are attached to the
strike teams to provide linguists, scouts, or fighters, based on the nature
of the hunter-killer operation. When required, conventional units can be
placed under the operational or tactical control of the hunter-killer unit
commander to facilitate task force and joint operations.
Results of this study suggest that the SOF community should:

havens. We can broaden our knowledge on this subject through a
larger, comprehensive study of foreign hunter-killer practices in enemy
safe havens to identify best practices the U.S. military could put into
use. The analysis derived from these measures should form the basis

of additions to the next doctrinal revision of COIN and irregular
warfare publications.
Explore the feasibility for the establishment of formal hunter-killerb.
organizations within the U.S. military. Currently, the U.S. Special Forces
perform this role as a result of specialized training and its organic
long-range mobility teams. Historically, effective hunter-killer units
fail when they are organized in an ad-hoc manner or task-organized
on the spot. They also are ineffective when they are merely converted
conventional units. Hunter-killer units require specialized training,
equipment, autonomy, unconventional leadership, and freedom of
action supported by the senior maneuver commander. One measure
could be to enhance the ranging concept in our Ranger formations;
another measure might include the development of hunter-killer
teams within the U.S. Marine Corps’ Special Operations Command
units. A third measure could include the designation of selected light
infantry units to perform hunter-killer operations. The success of
any of these additional measures relies on adherence to the derived
principles in the previous chapter.
Ascertain the impact of new technology enablers in aviation andc.
unmanned aerial vehicle systems, remote logistics, firepower, commu-
nications, and sensor and surveillance systems that would enhance
the capabilities of hunter-killer units and extend their endurance,
persistence, and presence.
As part of the shifting strategy to enable partners’ capability andd.
capacity, doctrine and procedures should be developed for provisions
in Security Force Assistance to create, build, equip, and employ foreign
and indigenous hunter-killer units.
Explore the dynamics of employing hunter-killer operations in consorte.
with human influence operations in order to implement psychological
action activities and to achieve desired behavioral effects on indig-

insurgents, ideologically driven, do not go away because they have been
separated from the populace. Successful insurgent strategy allows for them
to revert to a reconsolidation phase in an area safe for their operation. COIN
offensive forces—the hunter-killer teams—will still be needed to range deep
into the enemy’s domain to disrupt and destroy him.
